PROBLEM TO BE SOLVED: To provide a method for supplementing ultrasonic mechanical cleaning, focused on chemical decontamination of an irradiated nuclear fuel assembly. SOLUTION: A method for cleaning the irradiated nuclear fuel assembly includes chemically enhancing a technique, utilizing an apparatus including a housing adapted to engage a nuclear fuel assembly. A set of ultrasonic transducers is positioned on the housing, to supply radially emanating omnidirectional ultrasonic energy, to remove deposits from the nuclear fuel assembly. Any corrosion products that remain after ultrasonic fuel cleaning will have exposed surfaces that are susceptible to chemical dissolution. COPYRIGHT: (C)2009,JPO&INPIT |
